SUPPLY DEVICE FOR FILLING STATIONS OR STANDS.

Application filed February 17, 1921, Serial No. 445,685.

i same.

This invention relates to new and useful improvements in supply devices for filling stations or stands and has for its primary object the provision of pneumatic means for forcing liquid from a storage tank to the container of a filling stand or station so that the liquid may be dispensed from the container and obviate the employment of pumps heretofore ,used for such a purpose, and also reduce the expenditure of manual labor.

Another object of this invention is the provision of a sup 1y device for filling stations or stands of t e above stated character which will be simple, durable, and efiicient, and which ma be manufactured and sold at a comparative y low cost.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawtransparent container 3. The container 3 is.

provided with graduations to indicate the number of gallons of liquid contained therein.- The container 3 is connected to a discharge nozzle 4 to which an ordinary discharge hose 5 of a flexible nature may be connected for the purpose of directing the liquid from the container 3 into the fuel supply tank of an automobile or like vehicle. A combined supply and overflow pipe 6 is carried by the stand 1 and enters the container 3 and consists of a pair of sections 7 and 8. The section 7 enters the container 3. and has slidable connection with the section 8 and is rovided with a handle '9 for the purpose 0 regulating the height of the section 7 within the contalner so as to govern the amount of liquid to be retained within the container. The section 8 has connection with an auxiliary tank 10 located at a point foreign to the stand and the section 8 terminates adjacent the bottom wall of said auxiliary tank as clearly shown in the drawlngs.

The auxiliary tank 10 is provided with an intake pipe 11 connected with a valve 12 consisting of a casing 13 having in its bottom wall a clean out plug 14-. provided with a screw threaded aperture to receive a tube 15. The casing 13 is provided with a valve seat 1.6 adapted to be en aged by a valve 17, the stem of which is 0% hollow formation and slidably mounted upon the inner end of the tube 15. The valve stem adjacent the valve head is provided with vent openings 18. The intake port of the valve casing is connected to a pipe 19 having communication with a mainstorage tank 20 located in a plane slightly above the plane of the auxiliary tank so that the liquid contained within the storage tank may flow 1nto the auxiliary tank. The normal position of the valve 17 is unseated and moves into said position by gravitation.

The tube 15 is connected to an air supply pipe 21 whichextends to the stand 1 and from the stand to a suitable air supply. The

air pipe is provided with a valve 22 located at the stand for the purpose of controlling the passage of air pressure through said pipe to the valve 17 In operation, when it is desired to fill the container 3 air under pressure is allowed to enter the valve casing '13 or strike against the valve head for the purpose of moving the same into engagement with the valve seatand permits the auxiliary tank to be filled from the storage tank. The liquid now in the container3 may be disposed therefrom in the usual manner through the discharge nozzle 4. The container 3 has located therein a vent pipe 23 which extends from a point adjacent to the upper end ofthe container to a point adjacent the stand for the purpose of permitting the liquid in the container to readily flow out of said container under atmospheric pressure.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination, and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention what I claim is: f y

1. A supply device for filling stations comprising a stand, a container carried by said stand, a combined supply and overflow pipe connected to the container, an auxiliary tank connected to said pipe, a storage tank located in a plane above the auxiliary tank, a valve casing connecting said tank, a tube extending into the valve casing, a valve slidably mounted on said tube and adapted to engage a valve seat in the valve casing under pneumatic pressure and having a vent opening, and a pneumatic pressure pipe connected to said tube for seating the valve and for forcing liquid from the auxiliary tank to the container.

2. A supply device for filling stations including a dispensing container, a combined supply and overflow pipe communicating with the container, an auxiliary tank connected to said pipe, a storage tank located in a plane above the auxiliary tank, a valve casing establishing communication between the tanks and having a valve seat, a pneumatic tube extending into the valve casing and having its endlocated below the valve seat, a valve for said seat and having a tubular portion mounted for sliding movement below the head, said valve normally occupying a position away from the seat to permit fuel to passfrom the main tank to the auxiliary tank, and said valve adapted to be seated by air pressure from the tube to cut off the supply of fuel from the main tank to the-auxiliary tank and to place the fuel in the auxiliary tank under air pressure, and a control valve in the tube.

3. A supply device having a tank, conduit means through which liquid may travel thereto, a normally open closure valve for the conduit means, and means to admit a pressure medium into the conduit through the valve to serve dually to seat the valve to on the stem and provided with an opening close the conduit and to discharge liquid from said tank.

4. A supply device having a storage tank, an auxiliary tank in communication therewith and into which liquid flows by gravity therefrom, a normally open valve to control the flow of liquid from the storage tank to the auxiliary tank, and. means operable to admit a pressure medium throughthe valve into the chamber of the valve and into the auxiliary tank to serve dually to seat the valve and to discharge liquid from the auxiliary tank.

In testimony whereof I aflix my signature in presence of two witnesses.
